Yes, in my experience, overlays printed through Host Print Transform
tend to print in different positions, depending on the particular
MFRTYPMDL specified.
In one of my programs, I have worked around it as follows...
The DDS for the PRTF has this:
A OVERLAY(MYLIB/INVOICE -
A &PROVLDWN &PROVLACS)
(Mine is done via DDS, though you could do the same thing via parameters
on CRTPRTF, CHGPRTF or OVRPRTF if you prefer.)
Then my RPG code does this:
prOvlDwn = 0;
prOvlAcs = 0.25;
if (wkDev = 'PRT06');
prOvlDwn = 0.167;
endif;
So, for some devices, the "down" position is 0, and others it's 0.167.
This makes it line up in both cases. Sadly, I have it hard-coding the
device names of the devices that need a different offset (there's
probably a better way, but I haven't found it yet.)
My suggestion to you, therefore, is to make this "down" position
configurable. Ask your customer to do a test print, and if it's not
lined up, then change the down position and try again. If your overlay
position is specified via CRTPRTF like this:
CRTPRTF FILE(myfile) FRONTOVL(myoverlay 0 0)
Then your instructions to the customer might be as simple as saying "if
the overlay doesn't line up, then type this command:
CHGPRTF FILE(myfile) FRONTOVL(myoverlay 0.167 0)"
If you find a better solution, please let me know... because this is a
frustration of mine.
